Ukraine was not yet close to exhausting its capabilities to fight Russia, Wagner head Yevgeny Prigozhin said in an interview with Danish media on Tuesday, CNN quoted.

“Any offensive must be evaluated, as well as its results, after the enemy’s offensive potential has been exhausted. As far as I understand, Ukraine’s offensive potential is far from exhausted,” he said.

The head of a Russian private military company also said he did not know whether his forces would remain in Ukraine due to a dispute with the Russian Defense Ministry over contracts.

This comes after Russia’s Defense Ministry announced on Saturday that “volunteer formations” and private military groups would have to sign a contract with the ministry that would “give volunteer formations the necessary legal status” and create “unified approaches” to their activities.

The order does not mention Wagner’s group, but the move is seen as a way to rein in the influential military force. Prigozhin, who has publicly clashed with defense leaders, said the move did not concern Wagner.
